What is the first sign of a tsunami?
One of the signs of a potential tsunami is the occurrence of a very large earthquake that lasts for more than 20 seconds. If an area has been shaken by a very large earthquake, one should be on alert that shorelines located within the radius of the earthquake’s epicentre, may be hit by a tsunami.
How do tsunami kill you?
The energy of the tsunami runs through the entire depth of the ocean. It only becomes deadly when the ocean floor becomes shallow, and all that energy compresses into a smaller amount of water. Once it reached land, the raw energy of thousands of tons of water destroyed everyone and everything in its path.
Which country was hit hardest by the 2004 tsunami?

How do scientists know if a tsunami is coming?
Tsunamis are detected and measured by coastal tide gages and by tsunami buoys in the deep ocean. The tide gages measure the tsunami wave directly. In the deep ocean, sensors on the ocean floor detect the pressure signature of tsunami waves as they pass by.
Do animals know when a natural disaster is coming?
Animals have keen senses that help them avoid predators or locate prey. It is thought that these senses might also help them detect pending disasters. The United States Geological Survey (USGS) officially states, “Changes in animal behavior cannot be used to predict earthquakes. …

Can you predict a tsunami?
Earthquakes, the usual cause of tsunamis, cannot be predicted in time, but can be predicted in space. Therefore, tsunami prediction can only be done after an earthquake has occurred.
How do you know a natural disaster is coming?
Earth Scientists Use Fractals To Measure And Predict Natural Disasters. Summary: Predicting the size, location, and timing of natural hazards is virtually impossible, but now, earth scientists are able to forecast hurricanes, floods, earthquakes, volcanic eruptions, wildfires, and landslides using fractals.
